   rs-components.css — Rate Search component library
   ==========================================================================
   Primitives shared by every Rate Search module. Load AFTER rs-tokens.css and
   after unified.css (it refines .rs-loc, which unified.css defines).

   Rules of the house:
   - No colour/size literals. Everything reads an --rs-* token.
   - Every selector is scoped under .rs-page.
   - One class = one job. Modules compose, they don't restyle each other.
